  1. 16. Ectomycorrhizal fungi community shift along gradient from forest to clearcut : two field seasons after harvest of old growth Scots pine forests

    Master-uppsats, SLU/Dept. of Forest Mycology and Plant Pathology

    Författare :Linda Johannesson; [2023]
    Nyckelord :biodiversity; ectomycorrhiza; retention trees; ; fungi; clearcutting;

    Sammanfattning : It is known that the number of ECM decline and the community composition is altered by clearcutting. This study aims to investigate impacts at a more detailed scale. LÄS MER

  3. 17. The Effects of Material Properties in Saw Chain Cutting Efficiency Tests : Investigating the repeatability of cutting efficiency tests

    Master-uppsats,

    Författare :Petter Ödvall; Jakob Ivarsson; [2023]
    Nyckelord :Alternative Material; Cutting Efficiency; Density; Hardness; Knots; Moisture Content; Pinus Sylvestris; Polyethylene; Regression Model; Saw Chain;

    Sammanfattning : Manufacturers of saw chains continuously strive to increase the performance of their products by reducing cutting times and minimising the energy consumption required for cutting. However, the evaluation process through testing is problematic as several uncontrollable factors impact the results. LÄS MER

  4. 18. The effect of heat and UVC treatments on seed germination and seed-borne fungi of Pinus sylvestris, Pinus contorta and Pseudotsuga menziesii used in Swedish nurseries

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Wiktoria Breza; [2023]
    Nyckelord :seed-borne pathogens; artificial regeneration; conifers; thermotherapy;

    Sammanfattning : Pathogen free seeds are critical to produce healthy plants for forest regeneration. However, recent studies have shown that tree seed carry a high diversity of fungi including known and unknown pathogens. LÄS MER

  5. 19. Etablering och test av ett marteloskop i Vätteskogen, Skinnskatteberg

    Kandidat-uppsats, SLU/School for Forest Management

    Författare :Michael Cederhammar; Viktor Högström; [2023]
    Nyckelord :trädval; hyggesfritt skogsbruk; didaktik;

    Sammanfattning : Idag ökar intresset för alternativa skogsskötselmetoder till trakthyggesbruket, och ny kunskap om dessa metoder publiceras med allt högre frekvens av forskarkåren. För att implementera nya metoder i praktiken behövs verktyg som överbygger gapet mellan teori och praktik. Ett marteloskop är ett sådant verktyg. LÄS MER

  7. 20. Drought tolerance phenotyping using thermal imaging : high throughput phenotyping of Pinus sylvestris

    Kandidat-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Edvin Bertilsson; [2023]
    Nyckelord :Scots pine; Pinus sylvestris; drought tolerance; thermal imaging; high throughput phenotyping;

    Sammanfattning : Climate change is an emerging problem in the world. One of the many challenges that comes with it is an increase of droughts. Droughts cause stress for plants, which impact the growth. LÄS MER
